Homological Bounds of Gentle algebras

Representation Theory 2025-08-28 v1 Rings and Algebras

Abstract

This paper studies the homological bounds of gentle algebras, i.e., the upper bounds for the sum of the projective and injective dimensions of indecomposable modules over gentle algebras. We provide conditions under which this sum is strictly less than twice the global dimension, and as an application, we give a characterization of quasi-tilted gentle algebras.
